Tachometer and Time Calibration

Heat controlled incubators and centrifuges must rotate in a steady known speed in order to separate fluid to its components.

Apheresis uses a similar method. Centrifuge calibration is performed by using either an optic or a mechanical tachometer which counts the instrument’s speed and determines its rhythm.

part rotation speed in the industry indicated whether manufacture and testing procedure works according to standard. Differences in speed and rotation rhythm might indicate that a malfunction is occurring.
Identifying those changes early on could prevent machine down status. Another RPM and time calibration is preformed by counting items (bottles, tablets, stickers ect) passing by a counter.

Plane and chopper blades rotate in a steady pace to achieve elevation required to keep a vehicle in the air, in addition to a drop like shaped profile (the most aerodynamic shape in nature) through air. That what makes helicopters and planes move horizontally and vertically. The motor behind the blades must rotate in the right rhythm and according to throttle commands.
